SPECIFICATION forming part of Letters Patent No. 365,944, dated .Tuly 5,1887.

Application filedAugust 11, 1886. Serial No. 210,5?8. (No model.) I

To aZZ whom it may concern:

Be it known that I, GEORGE H. RYAN, a citizen of the United States,residing at Brockton, in the county of Plymouth and chusetts, haveinvented certain new and useful Improvements in WVireN ail Machines; andI do hereby declare that the same are fully described in the followingspecification, and illustrated in the accompanying drawings.

Thisinvention relates to improvements in machines for making wire nails;and it is carried out as follows, reference being had to theaccompanyingdrawings, whereon Figure 1 represents a plan view of themachine. Fig. 2 represents a front elevation, and Fig. 3 represents arear elevation, of the same. Fig. 4 represents a longitudinal section ofthe machine. Fig. 5 represents a cross section on the line A B in Fig.1, as seen in the direction of the arrows Xin said Fig. 1. Fig. 6represents cross-section on the line C D shown in Fig. 1. Fig. 7represents a cross-section 011 the line A B in Fig. 1, as seen in thedirection of the arrows Y in said Fig. 1. Figs S, 9, and 10 represent,respectively, end and side views and longitudinal section of one of thepointing and cutting dies. Fig. 11 represents wire nails made on themachine.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

To the floor in the workroom or other stationary object is secured thespindle or red a, having an adjustable collar, a, secured to it by meansof a set-screw or similar device. Loosely journaled on the spindle a,and resting on the collar a, is the spider or wire-reel support a, onwhich is located the reelof wire I), the latter being held in place onthe spider a, by means of the bent arms a a, secured in their lower endsto the spider a by means of thumb-nuts a a, as shown in Figs. 2, 3, and4.. By loosening the thumb-nuts a and turning the arms a about one -halfof a revolution the horizontal parts of said arms will be so located asto permit a reel to be placed on or removed from the spider a, as may bedesired. After the reel is placed on the spider the arms a are swungoutward and secured in position, as shown in Figs. 1, 2, 3, and 4..

State of Massa- (Shown made chilled, so as to resist their wearing outand at the same time be immovable relative to the said driving-shaft.

The cam d is for the purpose of actuating the wire-gripping mechanism.The cam d eccentric (Z actuates the cutting-off and nailpointingmechanism, as will hereinafter be more fully described. In addition tosaid chilled cams or eccentrics cast in one piece actuates thewire-heading mechanism, and the with the driving-shaft d, there issecured to it the cam or eccentric d, for actuating the nail clearingmechanism.

The heading mechanism for automatically heading the wire nail consistsof the metal bar 6, situated above the shaft (Z and adapted 7 to'movelongitudinally in guides c c on the frame 0, as shown in Fig. 4, saidbar having secured to it by means of nuts 6 e the block a, that isactuated by the chilled cam d,

which as it rotates in the direction shown by arrow in Fig. 4 causes thebar 0 to move backward against the influence of the wooden springs f f,secured together in their lower ends, and pivoted at f", as shown inFigs. 1,

2, 3, and 4, said springs serving to force the bar e forward as soon asthe lip d on the cam d has passed by the block 0'. The rear end I of thebar 6 lies in contact with the upper end of springf, as shown, and theupper end of spring f rests against the inner end of the 0regulating-screwf, that is screwed through the yoke f, the latter beingattached to rods f 5 f secured to and extending from the rear of theframe of the machine, as shown in Figs. 1, 2, 3, and 4. By adjusting thescrewf" the power of the-springs f f can be regulated at pleasure.

In a longitudinal recess in the forward end of the bar 6 is secured theheader e, the front end of which may be made flat for heading I00 5lower 70".

nails 1 2, as shown in Fig. 11,- or made cupshaped for heading nails 34, as shown in said Fig. 11, or otherwise shaped, according to style ofnail-heads desired. By removing the block 0 from the bar a andsubstituting for it another of a different height the stroke on the bar6 is correspondingly changed.

The mechanism for automatically feeding the .wire from the reel 1) tothe gripping mechanism isv carried out as follows: To one end of shaft dis secured the crank-plate g, having a groove, 9, in which is adjustablethe block 9, to which the crank-pin g is secured. To the said crank-pinis pivoted one end of the connecting or hooked feed-rod g, the forwardend of which has a handle, and a slot or looking-n0tch, g, forconnecting it to the bolt h on the feed-carrier 71 so that the feed canbe stopped instantly by lifting the rod, or the machine started withoutthe feed, the latter being provided with a bar, It, adapted to move'forward and back in the stationary guides 7t 7t, secured to the frame0, as shown in Figs. 1 and 2.

To brackets h h on the feed-carrier h is pivoted at 7L5 the lever h", towhich issecured the feed-dog h, (shown in Fig. 4,) and below the latteris secured to the feed-carrierh the feedblock h. (Shown in Fig. 4.)

7c is a sleeve having in its lower end horizontal projections It" is,adapted to rest in corresponding notches or recesses in brackets h 71 asshown in Figs. 1, 2, 3, and 4, said sleeve having located within it thespring and fol- (Shown in Fig. 4.) The upper end of the follower 7c iscupshaped to receive the lower end of the pressure-screw 70, that isscrewed through the lever h". (Shown in Fig. 4.)

The grip on the wire between the lower end of. the feed-dog h and blockit can be regulated simply by turning the pressurescrew k to the rightor left, as may be desired.

The operation of the wire-feeding mechanism is as follows: When thefeed-carrier h is moved by the action of the crank and rod 9 in thedirection of the arrow shown inflFig. 2, the lower inclined end of thefeed-dog If will slip on the wire by reason of the yielding propensityof the lever h,- but' as soon as the carrier h is moved in the oppositedirection the spring 70, acting on the outer end of lever h, will causethe wire to be clamped firmly between the lower end of the pointedfeed-dog h and the little block or plate h and thus the wire is fedforward a distance equal to the stroke'of the feed-carrier h. The amountof feed is regulated by adjusting the block 9 in the groove in thecrank-plate 9. Should it be necessary for any reasons whatever to stopthe feed of the wire during the running of the machine, this can be donesimply by taking hold of the handle 9 and lifting the latter far enoughso as to disengage the bolt h from the recess 9, and either to hold itin such inoperative position, or by moving the earrierh foradjustedtherein.

ward and allowing the part of the rod 9 to rest on top of bolt h, bywhich the rod 9* can move forward and back without imparting any motionto the carrier k. Another way of accomplishing the same object is totake hold of the horizontal projections Zc'k' in the lower end of thesleeve 70 and raise the latter against the influence of the spring 7csufficiently to cause the projections it k to be disengaged from thenotches in brackets if h, when the sleeve is may be removed entirely orswung out of position into the angle of the brackets h" it, if sodesired.

The gripping mechanism for automatically holding the wire while the sameis cut and headed is carried out as follows: In one piece with theframc'c, or secured thereto, is made the bridge 0, to which is securedby means of a screw or bolt, L, the lower adjustable gripper-die, L,which latter is preferably made cylindrical and provided with a seriesof peripheral grooves, L, that may vary in size and form according tothe size and shape of the wire that is being used in making the nails.The bolt L passes through a slotted perforation, 0, in the bridge a", bywhich the die L is capable of a vertical adjustment, and after beingadjusted to its proper position it is firmly secured to the bridge 0 bythe screw-bolt L, as well as by the regulating thrustserew L thatisscrewed through the lower eird of bridge 0 and has its upper end restingagainst the under side of the die L, as shown in Figs. 4 and '7.

Directly above thedie L is located the movable upper gripper-die, Z,journalcd on the screw-bolt Z, that is vertically adjustable in aslot-hole, Z, in the gripper lever Z, and provided with a series ofperipheral grooves or recesses, Z", and a vertically-adjustablethrustscrew, Z, for the purpose of adjusting the position of saidmovabledieZrelative to thelower die, L, according to the size of wireused in making the nails, so as to obtain a'firm grip on the wire whenthe gripper-lever Z is de pressed. The lever Z is arched in one end, asshown at Z in Figs. 1, 2, and 7, and there pivoted or hung to cars orprojections 0 c on frame 0 by means of pointed centers 0 c,passingthrough perforations in the ears 0 c and entering conical recesses inthe arched part Z, as shown, by which great accuracy and steadiness inthe motion of the gripper-lever are ob tained, and the arched end Zfurther serves to receive one of the knife-levers that are arranged inclose proximity to' the rear side of the gripperlever. c c areset-screws passing through the ears 0 0 for. securing the centers 0 e inplace on said ears after being properly To the free end of thegripper-lever Z is secured, by means of set-screw m, the block m, the.upper side of which is provided with a oup shaped or semi-sphericalrecess, 122-, (shown in Fig. 7 ,)in which fits one end of the ball-piecen, the other end of which fits into asimilar cup-shaped orsemi-spherical recess, 0', in the end of the rock lever 0, that ispivoted at 0 to the frame of the machine, and having its rear endactuated by the chilled cam d on driving-shaft d, as shown in Fig. 3.The plug in is made removable from the gripper-lever Z, so as to enablethe latter to be swu ng upward forthe purpose of adjusting the dies andknives. Thus the gripper-lever Z is operated in one direction-that is,toward the wire-so as to hold it firmly between the dies Z L by means ofthe cam d, and as soon as the latter ceases to act on the lever 0 thewire held between the dies ZL isliberated by the in fluence of springpressing on the verticallymovable rod 1), the upper end of which restsagainst the under side of the gripperlever Z, as shown in Fig. 7; andthus permits the feed of the wire to take place. In one piece with framea is cast a thrust projection, a, through which is screwed thethrust-serew 0 its inner end fitting in a block, 0, against which thegripper-lever Z is made to rest when the head ing of the wire takesplace. Said thrust-screw is provided with checknut 0. (Shown in Figs. 1and 3.)

1 make in the frame 0, directly below the cam d, a recess oroil-reservoir, 0 (shown in Fig. 6,) that contains a suitable lubricant,in which the cam d dips once during its revolution, and thusautomatically keeps the said cam properly lubricated. 0 is aregulatingscrew provided with a check-nut, as shown in Fig. 8, saidscrew being adjustabl y secured to lever 0, its lower end serving as astop against the top of frame 0, and thereby to limit the spread of thegripper-lever Z The mechanism for automatically cutting off and pointingthe wire is carried out as follows: In Figs. 8, 9,and 10, the cutter tisrepresented. There are a pair of these,and they are secured in asuitable manner, respectively,to the upper ends of the rock-levers PP,said levers having thrust-screws P P screwed through them to regulatethe position of the cutters relative to each other and to theirrespective levers, as shown in Fig. 5. The levers P P are pivoted to andsupported in their lower ends on the pointed centers P, passing throughperforations in the frame 0, their inner ends projecting into taperingrecesses iu the lower ends of said levers, as shown in Fig. 4, saidpointed fulcra P being secured in place by means of set-screws P, asshown.

Below the rock-levers P P is pivoted, by means of pointed centers 1q,the pressure-lever Q, as shown in Figs. 2, 3, 4, and 5, said centerspassing through perforations in the frame 0 and having their inner endsprojecting into tapering recesses in the lever Q, and secured 111 placeby means ofset-screws q q. Shown in Fig. 5.) The forwarchends of thelever Q are connected to the respective knifelevers P P by means of theuniyersallyjointed rods q q, as shown in Fig. 5, by which arrangement apositive reciprocating or oscillating motion is imparted to the knives ti from the rock-lever Q. The rear end of lever Q, is connected to therod r, the upper end of which is adjustably secured to the ring R, thatsurrounds the cocentric (F on shaft (1, and in this manner a positiveforwardandback motion to and from the wire to be cut and pointed isimparted to the knives t tfrom the driving-shaft by one cam or eccentricinstead of two, as usually done. The faces of the cutters t, as shown inFigs. 8, 9, and 10, are such as to compress and form the points of thenails cut off from the wire,as shown in Fig. 11.

S in Fig. 4-. is a clearing arm or finger for the purpose ofautomatically throwing off the finished nail in case the knives it!should happen not to entirely out through the wire, and saidclearingfinger is oscillated. or reciprocated by means of suitableintermediate connccting mechanism from the cam or eccentric d*, as iscommon in machines of this kind. By means of the movable pointed centers0 0 and P P a proper adj ustmentof the dies and cutters relative to eachother is obtained.

The operation of the machine is as follows: The wire isintermittentl yfed forward between the gripper-dies ZL' by the feed mechanism, as abovedescribed, and after being fed for ward the desired distance the wire isfirmly clamped between the said dies Z L by the mechanisnnas described,and while being held in said dies the wire is pointed and cut off by thecutters tt, and the remaining portion of the wire end is headed by theblow from the header 0", after which the wire is released from betweenthe dies Z L, a nail-length of wire is automatically fed forward, andthe dies 1 L made to close upon and hold the wire in place, after whichthe headed nail ispointed and cut off by the action of the cutters itand allowed to drop down through the machine, or de tached by the actionof the clearer S, if found necessary, after which successive portions ofthe nail-wire are headed, fed forward, pointed, out off, and delivered,as above set forth and described.
